In order to get quickly at the cylinder m as Well as at other arts of the machine, the diil'erent sections of the latter are made separable along the planes X-X and Y'- the said sections being supported externally by e esstiion frame, notshown. v

' Inasmuch as hoth of the above machines operate as cooling devices, owing to the lowering of the temperature due to the exoessive evaporation, further cooling of the solutions is not always necessary, but the application of artificial cold to the solutionsv line snow is produced, which passing into the flour assists in cooling it.

It, is a matter of experiment forthe miller to determine the quantities of any liquid or reagent desirable in a given batch of flour, and the extent to which the cooling of the products should he carried also best determined by the usual tests on the finished flour.
